The Influence of Heavy-vehicle on Urban Road Capacity

       WANG Xiao-sheng    YUN Mei-ping

Abstract: When heavy-vehicle taking a big proportion in mixed traffic flow，the existing standard vehicle equivalents and decreasing modulus of heavy-vehicle for capacity cannot reflect the actual traffic volume. Based on car-following model，the paper analyzed urban road capacity in different situations including car only，heavy-vehicle only, and mixed traffic flow when heavy-vehicle engrosses an obvious proportion. The result indicates that standard vehicle equivalents using 2~3 is unreasonable great for the below artery urban road. It’s more reasonable to use the ratio of urban road capacity in heavy-vehicle and cars as standard vehicle equivalents. when the proportion of heavey-vehicle is above 70 percent, the corresponding standard vehicle equivalents of mix traffic flow capcity can be used.
